Linking Shared Dimension does Time Out

[tboeni]

This issue occurs on TEST and INT. When trying to link the "Municipalities" Shared Dimension to the Region_ID in this cube using auto-fill and then adding the Shared Dimension to the list. "Update Mappings" will then time-out and return a unkown error message.
Linkage seems to (semi-)work but trying to publish causes a validation error which does not occur without the mapping.
Also the green chain symbol for properly linked dimensions does not show indicating for me something went wrong.
